Pack.FM is now live and in full effect (shouts to everyone who attended the INSANE Livestream launch). As promised, Pack kicks the exclusive content off with this unearthed gem – the first installment of PackFM‘s #FlowbackThursday series features perhaps one of his rarest appearances. Recorded for 24HourMC in 1999 with crew member Substantial, the duo also known as “Pack-Y-Stan” spit a “shit-load” of punchlines and head-nodding flows. This freestyle was previously unreleased.
